An apparatus for detecting a fertilizable period of mammals wherein electrodes (14, 14) are pressed onto the mucous membrane of vagina of a mammal to detect the concentration of sodium ions in the mucous membrane of vagina on the basis of the impedance between the electrodes (14, 14), and the result of detection is indicated on an indication means (20). When the concentration of sodium ions in the mucous membrane of vagina is nearly equal to that of water, it is indicated that ovulation will take place soon. |
